Julia Aquilia Severa (d. after 222) was the second and fourth wife of Roman emperor Elagabalus.

[1] Severa was a Vestal Virgin and, as such, her marriage to Elagabalus in late 220 was the cause of enormous controversy – traditionally, the punishment for breaking the thirty-year vow of celibacy was death by being buried alive.

This was possibly on the urging of Julia Maesa, the grandmother who had engineered Elagabalus' rise to the imperial throne.

Elagabalus then married Annia Faustina, a more generally acceptable choice to the senatorial elite.

[4] It is claimed by some historians,[weasel words] however, that many stories about Elagabalus have been exaggerated by his enemies, and so there is no certainty about what actually happened.
